Abstract The battery is provided with a can for storing a power generation means, a variable plate, which is linked and sealed in an opening part of the can with a gasket therebetween, and which is capable of deforming outward by an internal pressure of the battery, a terminal cap arranged on an uppermost part with respect to the variable plate, and a current breaking means, which is arranged between the variable plate and the terminal cap, and which is cut by a deforming pressure of the variable plate for breaking current. The current breaking means is provided with a traverse arranged, so as to cross above the center of deformation of the variable plate, an insulated printed board formed on the traverse including a breaking part and a via hole, an upper conductive thin film formed on the upper part of the insulated printed board, and a terminal part formed inside the via hole for energizing the variable plate and the upper conductive thin film.
